RESERVOIR v'-.EOR OILHSTM i necesa..-

` To all fathom t may concern.' i

Be it known that I, LoUIs -STocKsTRoM, a citizen of the United States, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Reservoirs for Oil-Stoves, of which the ffollowingis a specification, reference being had therein to the accompanying drawing. f

My invention relates to improvements in reservoirs :for oil stoves, the primary object of which is to provide a transparent reservoir for oil stoves, and means for supporting it, whereby the amount 'of oil in the xresemfpty ne of the troubles with this class of oilv stoves in the hands of the domestic, with` which the manufacturers have been con fronted for many years,.is :the burning, charring and destruction of the wick when .fthe oil supply is exhausted, there being no way for'lthe operator to determine that the vsupply should'be replenished. Operation under these conditions destroys the wick to a large extent and 'if repeated several 'timesI will require a new wick. Especially -is this true with the short wick type of oil stove here shown, where but alimited adjust-ment of the wick independent of the wick raiser can .be provided. It is also true to a somewhat less extent in respect to what is known to those skilled in the art as wickless oil stoves in which the asbestos ring is used.` The replacingpf the wick orof the asbestos ring is a disagreeable operation and the principal obiect' of this invention is to 'have con- Stantlyivisible before the operator i-n maintained level nil stoves, the level of the oil through the transparent glass reservoir, so that the operator has a constant reminder while around the stove of, the oil supply and when it needs replenishing to avoid burning of the wick or asbestos ringr when practically dry and its consequent destruct-lon.

ln the accompanying drawings: Figure 1 is a side view .oan oil stove withmy improved reservoir support combined -therew1th. Fig. 2 -islanenlarged perspective view showing .fthe reservoir support, a portien of the reservoir -n/nd the valve/plug in separated For the purpose oit illustration, l' fhave here shown my improved reservoir in iconnection with the short -wiektype of stove, but wish it understood that it is also intende'd for use connection 'with the 'wellknown wiekless stove with the same v of advantage. y v

Any suitable form ott framework 1, is provided and this carries one or more lburners 2 having thev ordinary wick'controtling member 26. An oil supply pipe .3 communicates with the burners and my invention coperates therewith to ,maintain the 'oil' at a predetermined level :in respect to the burner by the Well-known -barometric principle.

Myi-mproved .reservoir comprises a transparent glass receptacle or reservoir 4. yThe specific 'type here shown is a vertically disposed reservoir, and surroiniding this reservoir and held between ribs for projections 5` is a Aband 6. i This band 6 is provided with a 1handle 7 at opposite `sides-for convenient lifting vof the reservoir from'its support to be filled and to place it in its support after it is filled. V Other forms vof handles can be used and the handles dierently located without departing from the spi-rit and-scope of the generic invention here disclosed. The lower endy of this reservoir fis decreased'in size, as shown at .8 forming a shoulder 24, and this decreased end has permanently attached thereto a metal .collar 9, which extends inwardly and has a dependingrv mouth l0 integral therewith. The outer end of this mouth has a removablemetal stopper 11, provided with screw-threads 1Q, by means of which the stopper is removable.y This stop-per carries a lsuitable spring actuated valve 14, the spring 15 normally serving to hold the valve on thevalve seat 16. The valve 14 is provided -with a projecting stein 17, 'the operationof which will be presently referred to.

`My improved reservoir support comprises a bracket 18 having an opening 19, and depending from this bracket 19 is an annular wall 20 having its lower end contracted as at 21. Depending from this contracted end 21 is a Cup-shaped receptacle 22, which has its bottom connected with lthe end-23 in any, .suitable manner.y

y The opening 19 and the` depending an* nular wall 20 is of internal diameter greater than the diameter of the body of the reservoir 4,v whereby they lower end of the body of thev reservoir is'placed within this dependingf wall and the shoulder, `24 of the prevents it from being accidentally knocked from its support and broken, and provides a reduced receptacle or chamber 22, into which the reduced end of the reservoir and its metal mouth 10 project. When the reservoir is in the position shown in Fig. 1, the valve 14 is unseated by the stem v17, striking the bottom of the receptacle 22. lVhen the reservoir is lifted, the valve is automatically seated by a spring 15 and prevents any oil contained therein from running out. So long as the oil level in the reservoir 4 is above or near the bracket 18 its level can be seen by the operator. To enable the level of the oil in the transparent glass reservoir 4 to be seenwhen it is appreciably below the bracket 18 the frontl and .end of the wall 20 are each provided with an opening 25 of sujicient size to enable the -oil to be Seen therethrough and itslevel determined. Stoves of this type are eitherprovided with supporting legs (not shown) which will support the frame 11 a convenient heightI for the operator, or if not provided with legs (not shown) are set on a suitable support, which will maintain the stove in a convenient position for the operator. When supported by legs (not shown) or on a proper support, as indicated, the openings 25 will be vlsible to the operator without the inconvenience of stoopingto. any appreciable extent.

By means of the form of bracket and support here shown, the operator will be visibly and constantly reminded when'th'e level of the oil is below the bracket 18, and the bracket thus becomes an initialv or preliminary indicator and warning to the operator that thereafter care must be used inthe further use'of the stve to prevent destroying the Wick by burning it dry. At the same time, there remains suiiicient oil in the reservoir below the bracket for operating the stove a limited time thereafter if necessary, and the openings 25 provide a visible means of determining the level of the oil after the preliminary warning afforded by the disappearance of the level of the oil below the bracket 18.

It will be noted that the mouth of the glass reservoirv does not' directly communicate with the oilr conduit or pipe, but communicates with the cup-shaped receptacle 22.

(Dwingy to the fact that commercial kerosene oil used in connection with .these stoves is almost colorless,it is necessary to havea large body of oil visible in order to determine conveniently and quickly the level of the oil in' the reservoir.

' I am aware that attempts have been made to provide oil reservoirs of the maintained level typewith indicators by providing a strip of transparent glass or other transparent material in an opening in the wall of the reservoir, and also by attaching to the reservoir a glass tube communicating therewith in the manner of a boiler gage glass.

By means of a transparent reservoir, a large body of the oil is exposed to view at all times, making it quickly and readily apparent to the operator when it needs to be replenished, and which is not subject to the objections heretofore not-ed.

Having thus described my invention, what I claim and desire to secure by Letters Patent is: t

1. The vcombination with a .wick oil burner, of an oil conduit having one end communicating with the burner, an oil receptacle communicating with the other end of the conduit, and a transparent glass reservoir having a contracted lower end entering said receptacle, and a vertical and lateral support carried by the receptacle for the lower end of the reservoir, whereby the transparent reservoir is a` combined oil holder and oil indicator for the purpose described.

2. The combination with a `wick oil burner, of an oil conduit having one end communicating withthe burner, an oil receptacle communicating with the other end of the conduit, a transparent glass reservoir having a contracted lower end entering said receptacle, the upper end of the receptacle forming avertical and lateral support for the reservoir to hold it upright with the body portion exposed and said upper end of the receptacle having openings to expose the glass reservoir for the purpose described.

3. The combination with a .wick oil burner, of 'an oil conduit having one end communicating with the burner, antoil receptacle communicating with the other end vofl the conduit and extending upward and iared outwardly and upwardly forming a klateral and vertical support, said receptacle above the outwardly flared portion havingv openings, a transparent glass reservoir having a contracted lower end entering the oil receptacle and supported by the lateral and vertical portions thereof, whereby the glass reservoir can be seen approximately throughout its entire length, substantially as shown and described.
